Product Description ETU(NA-22)-80 imparts fast curing rate and safe scorch to CR. It is used as activator or assistant accelerator for other diene rubber with low or non sulfur. ETU(NA-22)-80 won’t bloom and can improve heat-resistance and mechanical properties of vulcanizate.


Processing Characteristics Generally, ETU(NA-22) powder adheres to devices easily, disperses difficultly in mixing process. However, ETU(NA-22)-80has good dosing and mixing property, and won’t cake at ordinary temperature and humidity. It has good fluidity, no irritating dust and no material loss. It keeps optimal activity of ETU(NA-22) and easily disperses in kinds of rubber compounds. Recommend that ETU(NA-22)-80 is added at last stage of mixing.


Dosage In general, 0.1 ~ 2.0 phr.


Applications ETU(NA-22)-80 is a universal accelerator for CR, CSM and CPE products.


Packaging Coextruded paper bags lined with plastic film, net weight 25Kg/bag.


Storage Store in a cool, dry, well-ventilated area away from sunlightfor up to 1 year.
